VESSEL.

SPECIFICATION forming part of Letters Patent No. 551,843, dated December24, 1895.

Application filed June 14, 1894. Renewed May 17, 1895. Serial No.549,707. (No model.)

To aZZ whom it may concern:

Be it known that we, HERBERT WVYOHER- LEY, residing at Parkville, andJOHN WIL- TON BARLOW, residing at Brooklyn, in the county of Kings andState of New York, have invented an Improvement in Vessels, of which thefollowing is a specification.

In the propulsion of vessels the power is usually exerted horizontallyand hence the bow of the vessel only rises upon the water according tothe contour or lines of the vessel, and in many instances theaccumulation of water at the bow seriously impedes the progress of thevessel.

The object of our present improvement is to cause the propelling powerof the vessel to lessen the draft at the bow. as much as possible, sothat the vessels bow tends to rise in the water instead of simplyplowing through it. With this object in view we provide at the bow ofthe vessel downwardlydnclined lifters either in the form of channels inthe vessel itself or flanges projecting from the surface, suchdownwardly-inclined lifters being preferably increasing curves and dyingaway below the body of the vessel so as to cause the forward propellingmovement of the vessel to lift the bow to a greater or less extent sothat the vessel rides more easily over the waves'and at the same time adownward pressure is exerted upon the water, causing the same to passunder the vessel and tend to lift the same, thereby lessening thedisplacement or increasing the buoyancy of the vessel.

In the drawings, Figure 1 is a side view illustrating the presentimprovement, and Fig. 2

is an elevation of thebow. Figs. 3 and at arecross-sections through theinclined lifters.

The vessel may be of any desired contour, and commencing at the bow Aand running backwardly at each side thereof are the inclined lifters B,which may be curved downwardly at an increasing curvature. Theseinclined lifters may be in the form of flanges projecting from andriveted to the vessel, as

at a, where the vessel is of iron, or they may be in the form ofchannels b cut in the sur face of the vessel and dying away graduallydownwardly. In either instance the horizontal and forward propulsion ofthe vessel causes the flanges or lifters to press against and tend toride over the water, thereby exerting a lifting action upon the bow ofthe vessel, and the water is pressed downwardly by the lifters and thequantity passing below the bottom of the vessel is increased, and thereis a tendency to lessen the displacement of the vessel according to theextent of surface presented by the lifting-flanges to the water as thevessel passes along through the water, and such flanges come in contactwith the water in its stationary condition, and the inertia of the wateris availed of in tending to elevate the bow of the vessel, as aforesaid.

We are aware that grooves have been provided for the surface of the boatand that in clinker-built vessels there are edges or shoulders runningfrom end to end of the boat and inclined. In these cases however thegrooves or shoulders at the back of the boat act in the reverse mannerto those at the front and neutralize any lifting effect that might beproduced at the bow.

W'e claim as our invention 1. The vessel having downwardly inclinedlifters at each side of the bow onlyto act only upon the water as it isparted by the bow to elevate said bow, as set forth.

2. The vessel having channels in its surface forming downwardly inclinedand curved lifters at each side of the bow only to act only on the wateras it is parted by the bow to elevate the bow of the vessel by themovement through the water, as set forth.

Signed by us this 11th day of June, 1894.
